A Jar Contains 10 Red Marbles

A random sample of n 3 marbles is selected from the jar.

A jar contains 10 red marbles.

Now the number of red marbles becomes. A draw the tree diagram for the experiment. If you remove marbles one at a time randomly what is the minimum number that must be removed to be certain that you have at least 2 marbles of each colour. The information shows that a jar contains 10 red marbles and 30 blue marbles.

A jar contains 4 black marbles and 3 red marbles. A jar contains 15 blue and 10 red marbles. If the first two marbles are both blue what is the probability that the third marble will be red. Find the probability of the given event please show your answers as reduced fractions.

10 x number of green marbles remains 30 hence total number of marbles becomes. A marble is drawn at random from the jar. 10 x 30 red marbles green marbles i e. There are 10 ways to succeed.

Calculating the probability of obtaining a red marble. A the marble is red b the marble is red or odd numbered c the marble is blue and even numbered answer by ikleyn 33701 show source. A if one marble is drawn at random what is the probability that it is red. The answer is.

Find the probability of the given event. 4 red 6 white and 10 blue. A jar contains 20 marbles. A jar contains 10 red marbles and 30 blue marbles.

A the marble is red b the marble is odd numbered c the marble is red or odd numbered d the marble is blue and even numbered. A jar contains 8 red marbles numbered 1 to 8 and 10 blue marbles numbered 1 to 10. A marble is drawn at random from the jar. If you reach in the jar and pull out 2 marbles at random at the same time find the probability that both are red 17 total marbles the 1st pick is 5 17 then 2nd is 4 16 the product is 5 68 makes no difference if you take 2 at a time or 2 different choices without.

There are 25 possible outcomes p red 10 25 2 5 b if two marbles are drawn randomly what is the probability that the first is red and the second blue if the first marble is replaced in. Two marbles are drawn without replacement. B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3. A the marble is red.

Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles. A marble is drawn at random from the jar. Suppose a jar contains 5 red marbles and 12 blue marbles. A jar contains 10 red marbles numbered 1 to 10 and 10 blue marbles numbered 1 to 10.
